Spitting out food can be a distressing and puzzling behavior for caregivers of people with dementia. This action is rarely intentional defiance; instead, it often signals an underlying issue the individual cannot communicate. Understanding the various factors contributing to this behavior is important for providing appropriate care, improving nutritional intake, and overall well-being.
Underlying Physical and Medical Reasons
Dysphagia, or difficulty swallowing, is a common physical issue, affecting up to 90% of individuals with dementia. This makes moving food from the mouth to the stomach challenging, leading to coughing, choking, or holding food. The weakening of swallowing muscles, a natural progression in dementia, further exacerbates this difficulty.
Oral health problems, such as sore gums, loose teeth, or ill-fitting dentures, can make chewing and eating painful. This discomfort can lead to food rejection. Dry mouth, often a side effect of medications, can also make food difficult to chew and swallow, causing the person to spit it out. Certain medications can alter taste perception, induce nausea, or affect motor control, making food unappealing or difficult to manage.
Cognitive and Behavioral Influences
Dementia significantly impacts the brain’s ability to process and respond to food. Individuals may forget how to chew or swallow, or misinterpret food as non-food items, leading them to hold or spit it out. This confusion can stem from a diminished ability to recognize hunger or thirst cues, or to recall when they last ate.
Sensory changes are a significant factor; dementia can alter a person’s perception of taste, smell, and texture, making familiar foods unappealing. A reduced sense of smell, for instance, directly impacts the ability to taste, potentially causing a loss of interest in food. Communication difficulties also play a role, as individuals may be unable to verbally express discomfort or dislike, resorting to spitting out food as a non-verbal cue. Confusion, agitation, or rejecting food when distressed can also lead to this action.
Environmental and Food-Related Considerations
External factors within the eating environment can contribute to a person with dementia spitting out food. The characteristics of the food itself, such as unfamiliar tastes, undesirable textures (e.g., lumpy, too dry, or too wet), or extreme temperatures, can prompt rejection. Food with mixed textures, like soup with bits, can be particularly problematic.
The mealtime environment significantly influences a person’s willingness to eat. Loud noises, excessive activity, or a distracting setting can overwhelm an individual, making it difficult to focus. Rushed feeding, uncomfortable seating, or poor lighting can also create an unpleasant experience, leading to food expulsion. A lack of contrast between the plate and the food, or a patterned dish, can make it challenging to distinguish what they are meant to eat.
Supportive Approaches and When to Seek Help
Addressing the reasons a person with dementia spits out food involves patience and observation. Modifying food texture to a softer, moist, or pureed consistency can make it easier to swallow, especially if chewing or swallowing is difficult. Offering smaller, manageable bites and allowing ample time for meals can reduce frustration and promote better intake. Creating a calm, quiet, and familiar eating environment, free from distractions, can help the person focus. Using high-contrast tableware can also make food more visually appealing and easier to identify.
Checking for oral pain, such as sore gums or ill-fitting dentures, and ensuring good oral hygiene are important first steps. If medications are suspected of causing taste changes or dry mouth, discussing alternatives with a healthcare provider may be helpful. Observing patterns, such as specific foods or situations that trigger the behavior, can provide clues for personalized adjustments. Seek professional medical advice if there are signs of choking, significant or unexplained weight loss, persistent refusal to eat, or indications of pain or infection, as these may signal more serious underlying conditions.
